Ast

Enum Ast 

Source
pub enum Ast {
    Root(Root),
    Condition(Condition),
    Action(Action),
    ActionDescription(Description),
}
Expand description

An Abstract Syntax Tree (AST) that describes the semantic structure of a bulloak tree.

Variants§

§

Root(Root)

The root node of the AST.

§

Condition(Condition)

A condition node of the AST.

This node corresponds to a junction in the tree.

§

Action(Action)

An action node of the AST.

This node corresponds to a leaf node of the tree.

§

ActionDescription(Description)

Additional action description.

This node can only appear as a child of an action.

Implementations§

Source§

impl Ast

Source

pub fn span(&self) -> &Span
